Energy Storage for a Sustainable Home

The world currently consumes 20 trillion kWh of energy annually.

Enough energy to power a single family home for 1.8 billion years or supply energy to a nuclear power plant for 2,300 years.

Of all the fossil fuel consumed alone in the United States, one third is used in transportation and another third goes to electricity production. The US electric power sector alone produces over 2,000 million metric tons of CO2 which is like burning 225 billion gallons of gas. The EPA says it would require 1.6 billion acres of US forest to negate the environmental damage.

Living in the Azores

We live in a Biosphere one that we should protect and we should be a key player in the revolution of sustainable energy.

If the government were to assist us we would all be able to use a home battery that charges using electricity generated from solar panels, or when utility rates are low, and powers your home in the evening. Securing your home against power outages by providing a backup electricity supply. A system that offers independence from the utility grid and the security of an emergency backup.

Once we are able to rely on renewable energy sources for our power consumption, the top 50% of the dirtiest power generation resources could retire early. We would have a cleaner, smaller, and more resilient energy grid.

Does such a system exist?

Yes it does and it is so very affordable. A system developed by Tesla Energy a system that will change our world a system that makes our world a better place.

Tesla introduces Tesla Energy, a suite of batteries for homes, businesses, and utilities fostering a clean energy ecosystem and helping wean the world off fossil fuels.

Tesla is not just an automotive company, it’s an energy innovation company. Tesla Energy is a critical step in this mission to enable zero emission power generation.

With Tesla Energy, Tesla is amplifying its efforts to accelerate the move away from fossil fuels to a sustainable energy future with Tesla batteries, enabling homes, business, and utilities to store sustainable and renewable energy to manage power demand, provide backup power and increase grid resilience.

Tesla is already working with utilities and other renewable power partners around the world to deploy storage on the grid to improve resiliency and cleanliness of the grid as a whole.

Tesla Powerwall is a rechargeable lithium-ion battery designed to store energy at a residential level for load shifting, backup power and self-consumption of solar power generation. Powerwall consists of Tesla’s lithium-ion battery pack, liquid thermal control system and software that receives dispatch commands from a solar inverter. The unit mounts seamlessly on a wall and is integrated with the local grid to harness excess power and give customers the flexibility to draw energy from their own reserve.

The battery can provide a number of different beneﬁts to the customer including:

Load shifting – The battery can provide ﬁnancial savings to its owner by charging during low rate periods when demand for electricity is lower and discharging during more expensive rate periods when electricity demand is higher

Increasing self-consumption of solar power generation – The battery can store surplus solar energy not used at the time it is generated and use that energy later when the sun is not shining

Back-up power – Assures power in the event of an outage

Powerwall increases the capacity for a household’s solar consumption, while also offering backup functionality during grid outages.

Powerwall is available in 10kWh, optimized for backup applications or 7kWh optimized for daily use applications. Both can be connected with solar or grid and both can provide backup power. The 10kWh Powerwall is optimized to provide backup when the grid goes down, providing power for your home when you need it most. When paired with solar power, the 7kWh Powerwall can be used in daily cycling to extend the environmental and cost benefits of solar into the night when sunlight is unavailable.

Tesla’s selling price to installers is $3500 for 10kWh and $3000 for 7kWh. (Price excludes inverter and installation.) Deliveries begin in late Summer.

Energy Storage for a Sustainable Home

Powerwall is a home battery that charges using electricity generated from solar panels, or when utility rates are low, and powers your home in the evening. It also fortifies your home against power outages by providing a backup electricity supply. Automated, compact and simple to install, Powerwall offers independence from the utility grid and the security of an emergency backup.

Solar Powered Day and Night

The average home uses more electricity in the morning and evening than during the day when solar energy is plentiful. Without a home battery, excess solar energy is often sold to the power company and purchased back in the evening. This mismatch adds demand on power plants and increases carbon emissions. Powerwall bridges this gap between renewable energy supply and demand by making your home’s solar energy available to you when you need it.

Avoid Paying Peak Rates
Power companies often charge a higher price for electricity during peak evening hours than overnight when demand is low. Powerwall can store electricity when rates are low and power your home when rates are high.

Energy Security
Powerwall automatically switches to battery power in the event of an electric company outage, bringing peace of mind to those who live in areas prone to storms or unreliable utility grids.

Clothes Dryer
3.3 kWh each use

How it Works

Home solar installations consist of a solar panel, an electrical inverter, and now a home battery to store surplus solar energy for later use.

Home battery Powerwall stores surplus electricity generated from solar panels during the day or from the utility grid when rates are low.

Inverter Converts direct current electricity from solar panels or a home battery into the alternating current used by your home’s lights, appliances and devices.

Contained within Powerwall’s outdoor-rated enclosure is a rechargeable lithium-ion battery, a liquid thermal management system, a battery management system and a smart DC-DC converter for controlling power flow.

How to Buy

Powerwall begins shipping this summer and requires installation by a trained electrician. Reserve yours today and you’ll be contacted this summer to arrange installation.
